DE \VANE B. SMITH, OF UTIOA, NEW YORK.

WAGON-BOLSTER SPRING.

SPECIFICATION forming part of Letters Patent No, 393,345, dated November20, 1888.

Application filed November 10, 1887. Serial No. 254.837.

T0 at whom it may concern.-

Be it known that I, DE \VANE B. SMITH, of Utica,in the county of Oneidaand State of New York,have invented certain new and useful Improvementsin Wagon-Bolsters, Saddles, and Torsion-Springs; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My invention consists inthe combination of a bolster, saddles,andtorsion-springs arranged as hereinafter set forth and claimed.

Figure 1 represents a perspective view of a bolster, the saddles, thetorsion-springs, and the sub-bolster. Fig. 2 represents a perspectiveview of a bolster, and the torsion-springs, showing the sub-bolsterremoved. Fig. 3 represents a perspective view of one of the saddles.Fig. 4 is a perspective end view of one of the saddles of modifiedconstruction and a section view of the torsion-springs and theirconnection with the saddle. Fig. 5 represents a similar view to Fig. 4,showing a saddle of a modified construction; and Fig. 6 represents asimilar view to Fig. 4: of a still further modified construction. Fig. 7is a perspective view of a link for connecting the saddles and thesprings.

The purpose of my invention is to furnish saddles for ordinary bolsterson wagons, on which torsion-springs are mounted, as hereinafter morefully pointed out.

In the drawings, 1, Figs. 1 and 2, represents an ordinary wagon-bolster.

2 2 represent the stakes in the bolster.

3 3 represent torsion-springs formed in two parts or sections, the twoparts forming a complete spring. Each section is formed of a singlepiece of steel rod of the required size, length, and temper. Eachsection has a loop, 4 4., in the rod. The outer ends of each section arebent at an angle to' the loop, as shown at 5 5, the ends turningoutward. At the inner end of the loop in each section a depression isformed in the rod forming the spring to allow one of the sides of theloop to fit therein, as shown at 6 6, so that the rods forming the loops(No modcLl I of the two'sections are brought on the same horizontalplane, in order to fit the under side ofa wagon box or sub-bolster, a,as shown in Fig. 1. The sections of the torsion-springs are held to theunder side of the sub-bolster or boX and are adjustable therein byengaging clips 7 7 7, for partially engaging the rod forming thesprings, which are provided with perforations for receiving bolts 9 9.The sections of the spring are free to be horizontally adjusted underthe clips,when the springs may be lengthened or shortened, and whenadjusted the same may be rigidly held by tightening the nuts on thebolts.

I provide at the outer ends of each section of the torsion-spring hooks10 10, for receiving intermediate links, 11 11, which connect withcircular hooks 12 12 on the extension-arms of saddle 13, provided withprojecting shoulders 14 14, fitting the opposing edges of the bolster,on which the same is mounted crosswise of the bolster, each saddle beingplaced in close proximity to stakes 2 2, so that slots 15 15 in each endof the sub-bolster engage the sides of the stakes to secure steadinessand accommodate the vertical reciprocal action of the springs whensubjected to strain.

Another feature of my invention consists in providing slots 16 in thecircular hooks on the arms of the saddle for receiving and retaining theprojecting shoulders 17 17, Fig. 7, in the circular hooks, neck 18fitting loosely in slots 16 16 in the hooks, the looped end 19, Fig. 7,

engaging hooks 1O 10 on the ends of the torsionsprings, whereby thesaddle may be attached and detached from the spring. This, however, maybe accomplished in another way by means of links 11 11, which in someinstances may be considered preferable.

The superior advantages arising from the use of my saddles may beattained by the use of inclined slots 20, Fig. 6, in the ends of thesaddles for receiving the ends of the torsionsprings, which are free towork therein, and the same result may be had by the use of triangularopenings or slots 20 20, Fig. 5.

I do not claim to be the inventor of the tor sion-springs shownin Fig.2, as this is old; but my invention consists in the peculiar arrangementof the saddles and the connection of the springs therewith as applied towagon-bolsters.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination of a saddle adapted to ride crosswise of awagon-bolster, having projecting arms extending beyond the opposingedges of the bolster, torsion-springs held to a sub-bolster, andconnecting-links adapted to connect the arms of the saddle with thetorsion-springs.

2. The combination, with a wagon-bolster, of the saddle placed crosswisethereof, having downwardprojecting shoulders for engaging the opposingedges of the bolster, the arms of the saddle extending beyond the edgesof the bolster and at right angles thereto, provided with circularslotted hooks on the ends of the arms, the links having shoulders andneck for engaging the slotted hooks, and the torsionsprings connectedwith thelinks, substantially as set forth.

3. The combination of a sub-bolster having slotted ends adapted toengage and slide between the stakes of a wagon, torsion-springs securedto the sub-bolster and having the ends thereof adapted to be carried bya saddle crosswise of the wagon-bolster,and asaddle adapted to ride thebolster crosswise,having shouldered projections adapted to engage theopposing sides of the bolster, and having arms projecting beyond thebolster for carrying the end of the springs, substantially as set forth.

at. The combination ofthesub-bolster adapted to move between the stakesof a wagon, torsionsprings secured to the sub-bolster, the ends thereofconnected with the saddle, and a saddle having shoulders to engage theopposing edges of the bolster, and arms extending beyond the edges ofthe bolster adapted to engage the ends of the torsion-springs.

In witness whereof I have aflixed my signatnre in presence of twowitnesses.

DE \VANE B. SMITH.
